TV Series


TV Series
Applications

In Italian language TV means “TIPO VECCHIO”(old type) because this series of couplings is the first that MB began to produce from 1956 on his own drawings: TV series is well known in Italy and now MB is the only producer of it. These couplings are suitable for any hydraulic application in industry and in agriculture: the hardiness and the wide range of sizes are their peculiar features. The 1.1/4”, 1.1/2” and 2” sizes are also available in brass and in stainless steel AISI 316.
